Note: If a KLM or KTM fuse holder without a fuse is connected to a load, this situation causes the red LED to light and the alarm contacts to change states, same as would occur in a fuse failure. For other types of fuses (TPA and GMT), if a fuse holder without a fuse is connected to a load, the corresponding sensor remains inactive and no failure is indicated.

1.16 Power-On Indicator

An optional visual power-on indicator (green LED) for each power bus is mounted near the center of fuse platform front panel. If present, the LED, when lighted, indicates that power is being applied to the bus input connectors. An unlighted LED indicates that power is not being applied. The power-on indicator LED can be replaced in the field.

1.17 Fused Equipment Designation Card and Holder

Two fuse designation cards, shown in Figure 4, and a card holder with a clear plastic cover are provided with the fuse platform. The card holder may be attached to either the fuse platform, the fuse platform mounting brackets, the rack, or a suitable surface close to the fuse platform. One of the cards may be filled out with circuit information for each of the circuits and inserted in the card holder. The card holder has a pressure-sensitive adhesive backing for attachment. Additional fused equipment designation cards, card holders, and plastic covers can be ordered separately if required.

1.18 Voltage Designation Label

A voltage designation label, shown in Figure 5, is provided with the fuse platform. The label may be filled out with the actual voltage present on the buses and placed on the fuse platform. The voltage designation label has a pressure sensitive adhesive backing for attachment.
